This spear is solid, I move a mix of round bales and large square bales. It works well for both. The only issue is one of the chains has already broke after a month of use.
This piece of equipment is well built and does a great job for me. I would have rated it a 5, but it was shipped with chains too short to wrap around my Case 580 backhoe bucket. I assume the spear attachment is meant for little smaller farm tractor buckets. Anyway after putting additional pieces of chains and some bolts, I'm happy and much safer than I was with my pallet forks.
